Be it known that we, JAMES P. SIBLEY and ARTHUR WALSH, of Bennington, in the county of Bennington, and State of Vermont, have invented a new and useful Improvement in Governors for Tater-Wheels; and we do hereby declare that the following is a. full, clear, and exact description thereof,which will enable others skilled injthe art to make and luse the same, reference being had to the accompanying drawings, forming part of this specification, in which# Figure 1 is a vertical section of ourinvention, taken in the line as g. 2.

Figure 2 a horizontal section of the same, taken in the'line y y, fig. l.

Figure 3 is an elevation of a portion of the same.

Similar letters of reference indicate like parts.

This invention relatesto a new and useful improvement in governors, designed more especially to be applied to water-wheels.

And it consists in a novel construction and arrangement of parts, as hereinafter fully shown and described, whereby several advantages are obtained, which we set forth in the followingdescription.

In theaccompanying sheet ofdrawings- A represents the framing of the device, which maybe constructed in any proper manner to support a vertical tubular shaft, B, whichreceives a rotary motion from a driving-shaft, C, by means of bevel-gears D D', both of which are shown in fig. 3.

On the upper part of the tubular shaft B, there is attached, by set-screws a a, a head, E, in whichTat opposite ends, the arms F F of two balls G G are secured by pivots the inner ends of said arms being fitted in a I shaft, H, which is within the tubular shaft I3, and turns with it, the shaft H being allowed to rise and fall freely in B. v

On the `lower part of the tubular shaft B, there is fitted a. collar, I, which is allow-edito rise and fall freely on B, and this vcollar is connected to the shaft I-I by pins c c, which pass through vertical slots d d inB, and into I-I, (sce fig. I.)

This collar Ilias a groove, e, made in it circumferentially, to receive the pin fof a lever, J, which is attached to a shaft', K, having its bearings on the framing A.

On the lower part of the tubular shaft B, there is keyed an eccentric, I, which operates an arm, M, connectedto slide N, the eccentric and arm communicating a reciprocating motion to the slide from the shaft B.

This slide N has two pawls, O O', attached toit. which are in'opposition, as shown in iig. 1, and engage,- one at a time, with the under side ofa ratchotwheel, I); on a shaft, Q. i

It is a cylindrical shell, the hub g of which is fitted loosely on theY shaft Q.

This shell laps over the periphery of the ratchet-wheel I, and it has a section or portioncut out'or removed at its` under side, as shown at L in fig. 1.

This shell R is designed tothrow the pawls O O out of gear with the ratchct-wheel-P, which it does alternntely, as will be presently shown.

The lower part of the shelhis connected, by a rod, S, with the lower end of a pendent arm, T, attached'to the shaft K, the latter having a pendent arm, U, at one/end of it, behind which a pin, L', from a shaft, V, projects, said shaft being fitted und allowed to slide in bearings in the upper ends of uprightsjj.

This shaft V is connected, at one end, by a metallic strap, W, with a spool, X, placed loosely on one end ofthe shaft- Q, and secured therein, with a great-er or less degree of pressure, bya nut, Y.

On the shaft V there is placed a spiral spring, Z, the use of which will presently be shown.

-When the governor isfin operation, the pawl O, when engaged with the ratchet-wheel P, and the slide N, moves in the direction indicated by arrow l, turns the wheel P in the direction indicated by arrow '2, and when the wheel P turns in this direction, thegate is raised by means of gearing from the shaft Q. .When the slideN moves in the opposite direction, as indicated by-arrow 3, and the pawl O is engaged with'wheel'R the-pawl O being disengaged therefrom, the wheel P is turned in the direction, indicated by arrow 4, and the gate will be lowered' Y A is a slide, which isYplac-ed Aunderneath the wheel P, and is designed for throwing the pawl O out of gear with wheel P, when it is necessary to close the gate suddenly, and stop the wheel.

When the wheel is rotating at a slow speed, or below its maximum, the balls G G will be down or depressed, and the shell R in such a position that the .pawlOwill be disengaged from wheel P, and the pawl O engaged with it. Consequently the wheel P will be turned by the pawl O, in the direction indicated by arrow 2, and the gate will consequently be raised, and more water let upon the wheel, until the desired speed is obtained.

In case the wheel runs too fast, the balls G G will rise, and, with them, the shaft H and collar I, and the lever J will turn the shaft K, so that the arm T and rod S will turn the shell R in the direction indicated by arrow 5, so that the pawl O will be disengaged from wheel B, and the pawl O engaged with it under the inuence of a spring, ax. The wheel P will consequently be turned in the direction indicated by arrow 4, as tbe slide N moves in the direction indicated by arrow 3. l

In the event of the wheel rotating at a slow speed, caused vby an insuilicient supply of water, the gate is relieved, after being raised to its fullest extent, in the'following manner:

The friction between the spool X and the shaft Q causes the spool to turn with shaft Q, and the strap W winds upon thespool, thereby actuating the shaft K each time the slide N moves in the direction of arr-owl".

This movement of shaft K will raise the balls G, and actuate the shell R, so that the dog O will be disengaged from wheel P, the balls centre'forming the friction of spool X, so as to hold the shell in a certain position, and prevent the movement of wheel P until the requisite supply of water acts upon the wheel, and the speed of the latter will raise the -balls G a greater height, and move the shell R, so as to cause the pawl O to engage with wheel P, and the gate to be lowered. v

Having thus described our invention, we claim as new, and desire to secureby Letters Patent- 1.` The arrangement of the eccentric L,on shaft B, for operating slide N, and the collar I, tted on shaft B, and connected by shaft K, and levers J T, and arm S, for the purpose of operating the shell R, substantially as specified.

2. The slide N, provided with the pawls O O', in connection with the wheel P, all arranged substantially as set forth.

3. The metallic strap W, attached to the spool X, on shaft Q, connected with shafts V and K, all arranged as specied.

4. The slide A', when arranged or placed in relation with slide N and wheel P, substantially as specified.
